/*! \brief Create an OpenCL context.
 *
 *  An OpenCL context is created with one or more devices. Contexts are used by
 *  the OpenCL runtime for managing objects such as command-queues, memory,
 *  program and kernel objects and for executing kernels on one or more devices
 *  specified in the context.
 *
 *  \param properties is reserved and must be zero.
 *
 *  \param num_devices is the number of devices specified in the \a devices
 *  argument.
 *
 *  \param devices is a pointer to a list of unique devices returned by
 *  clGetDevices. If more than one device is specified in devices,
 *  a selection criteria may be applied to determine if the list of devices
 *  specified can be used together to create a context.
 *
 *  \param pfn_notify is a callback function that can be registered by the
 *  application. This callback function will be used by the runtime to report
 *  information on errors that occur in this context. This callback function
 *  may be called asynchronously by the runtime. If \a pfn_notify is NULL,
 *  no callback function is registered.
 *
 *  \param user_data will be passed as the user_data argument when \a pfn_notify
 *  is called. \a user_data can be NULL.
 *
 *  \param errcode_ret will return an appropriate error code. If \a errcode_ret
 *  is NULL, no error code is returned.
 *
 *  \return A valid non-zero context and errcode_ret is set to CL_SUCCESS
 *  if the context is created successfully or NULL with the following
 *  error values stored in \a errcode_ret:
 *    - CL_INVALID_VALUE if \a properties is not zero.
 *    - CL_INVALID_VALUE if \a devices is NULL.
 *    - CL_INVALID_VALUE if \a num_devices is equal to zero.
 *    - CL_INVALID_DEVICE if \a devices contains an invalid device.
 *    - CL_INVALID_DEVICE_LIST if more than one device is specified in
 *      \a devices and the list of devices specified cannot be used together
 *      to create a context.
 *    - CL_DEVICE_NOT_AVAILABLE if a device in \a devices is currently not
 *      available even though the device was returned by clGetDevices.
 *    - CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources
 *      required by the runtime.
